As many of the people in review has told about my flaws and what i can improve, i want to thank them for this honest review. I added the interactive buttons with emoji and also added indivisual pages for every action. some of you also compared my project to ILovePdf for them i want to say that in my project everything stays in your device everything is processed in your browser unlike this companies which upload your pdf to server. it gives some advantages to my project ie. safe, private, secure, fast.
